Force placement of sum operands over index

I want to force the operands of a sum to be placed above an "extended" (longer than usual) index, instead of increasing the width of the sum (in the example, see the sums in (2), which are much wider than in (1), because of the different index). I need this for space reasons, the formula is bigger than in the MWE. Do you have any ideas how to achieve this?

 &= sum_m=1^55 10,000 cdot Z_m + 7,000 cdot K_m \
 &= sum_i in m 10,000 + sum_j in k 
7,000
endalign

Use mathclap from mathtools package.

%usepackageamsmath
usepackagemathtools

beginalign
 texttextbfTotal Cost 
 &= sum_m=1^55 10,000 cdot Z_m + 7,000 cdot K_m \
 &= sum_mathclapi in m 10,000 + sum_mathclapj in k 
7,000
endalign

      @ncw, no problem. Just pay attention in my comments on trailing spaces. Also, only textbf is enough.

    A variant, with the smashoperator command from mathtools – and some improvements with siunitx, so the comma separator in numbers doesn't add a space.



    smashoperator can take an optional argument, [l] or [r] which are equivalent to mathlap or mathrlap respectively. I demonstrate it in a $3$rd equation:



    documentclass[12pt]article
    usepackagemathtools
    usepackagesiunitx

    begindocument

    sisetupgroup-digits = integer, group-separator=,, group-minimum-digits = 4
    beginalign
     textbfTotal Cost % no trailing space inside braces
     &= sum_m=1^55 num10000 cdot Z_m + num7000 cdot K_m \
     &= smashoperatorsum_i in mmid Z_m = 1num10000 + smashoperatorsum_j in kmid K_m = 1 num7000 \
     &= smashoperator[r]sum_i in mmid Z_m = 1 num10000 + smashoperator[l]sum_j in kmid K_m = 1 num7000
    endalign

                A variant, with the smashoperator command from mathtools – and some improvements with siunitx, so the comma separator in numbers doesn't add a space.



                smashoperator can take an optional argument, [l] or [r] which are equivalent to mathlap or mathrlap respectively. I demonstrate it in a $3$rd equation:

                      How many registers does an x86_64 CPU actually have?

                      Image
                      Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
